Description: |
| Improvements to the inventor's patent 2,826,540. These two patents together can be considered the seminal patents related to electrochemical machining, which involves passing a high current through the workpiece and a rapidly rotating disc with an electrolytic fluid in the small gap between the two. The workpiece is connected to the positive side of the DC power and the disc to the negative. The voltage is low to minimize arcing but the current is generally in the range of 200 to 1000 amperes per square inch, and the material removal rate will be proportional to the current density. The patent provides a number of refinements to minimize arcing and to provide a smooth finished surface while achieving high rates of stock removal. |
